SLIDNG-DOOR FSTENER.

Liaoning l Toall 'whom t may concern:

Be it known that we, FiNrs W. Cimiionn and ORA L. l/VILsoN, citizens ot the'United States, residing at Cecilia, in the county of Hardin and State of Kentucky, have invented 'certain new and useful improve,- ments in Sliding-Door Fasteners, of which the following is a specification.

The present invention relates to improvements iii"v locks and has particular reference to a self-acting lock adapted for-use in connection with sliding or reciprocaftory doors,

, such-as car doors.

An importantobject df the invention is to provide means whereby acari' door which has been left partly or wholly opemnpon moving to the closed position, due to bumps or jars upon the car, will be securely locked in such closed position whereby the door is prevented from being subjected to unnecessary strains.

l Afurther object of the invention is to provide a lock-of the above mentioned chara'cter, which is simple in constructioininex- .pensive to manufacture, strong, and durable. l 'Other objects and advantages of the invention will be apparent'during the course oi the following description.

In the accompanying drawings forming a` A part of this specification and in which like wheels 12, traveling upon a track 13.

In the drawings, wherein .for the purposeof illustration is shown a preferred embodiment of our invention, the numeral 10 des.- ignates the body of a car having a sliding or reciprocatory door 11, supported nby i. G- cured to the side of Hthe body 10 adjacentV one side ofthe door opening is a' door jamb 14, having a recess formed therein. Secured to the inner edge of the beam 14 is a pro'- tecti-ng plate 16, as shown. This protecting plate, as more clearly shown in Fig. 11, is

provided with an opening 17, .for apurpose to be described.. Mounted within the recess l5 is a control memberlor lever 189 provided l Specification of Letters vatent.

at itsupper en d with apertured knuckles 19, receiving a pivot element or bolt 20, se-

cured to the beam 14. lt is thus apparent that the control member 18 is pivoted to swing in a vertical plane. Arranged within the recess 15 inwardly of the control meinber 18 is a bolt-spring or bar 21, the lower end of which is attached to the beam 14 by Theupper end of the bolt-spring or bar 21 lits loosely within a U-shaped member .-or .staple 23l rigidly attached to the upper portion of the control member v18 nearand spaced beneath its pivot 20. The bolt spring or bar 21 is norinallystraight and serves to normally retain the control member 18. in the inner vertical position.

Meansare provided to lock the control" member 18 in the inner or vertical position,

carried by the control member 18I and operating in a longitudinal recess 25 thereof.

This latch'bolt has its lower end beveled and 80 projects into la recess 26 and'is` adapted for detachable engagement with a staple or a pertured member 27 held stationary to the door jamb 14:.' Thelatch bolt 24 is'moved downwardly by a compressible coil spring 2S, and may be moved upwardly by a lateral extension ori'inger hold 29, sliding between apertured lugs or ears 30 lformed integral with the control member18. A key"31 is inserted through the apertures of the member 29 andthe lugs 30' and has a head 32' at one end and an aperture 33 at the other end for receiving a seal 34. Vihen thekey 31 is in placejitl is obvious that the control member 18 is locked against upward movement. y

Secured to the door 11 is a door bolt 35,

having a hooked head 36, adapted to engage behind the bolt-spring 21. rl`he control member 18 has a recess 37 adjacent the door bolt 35, which will permit of the 'yielding action of the bolt-spring 21, and the .passage of the head of the doorbolt, the

ber 18 to the outer position, to e'n'ect a disengagement between thehoolred endlof the door-bolt 36an`d the bolt-spring or fijar 21. It is'apparent that the bolt-spring 21 serves a double function, to 'Wit, as automatic means to'return the control member to the inner vertical position, and to lock the doorbolt against movement.

It is to be understood that the form of our invention herewith Shown and described is to be taken as a .preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to Without departm'g from the spirit of the invention or Having thus described oui invention, We claim:

1.v In a lock of the character described,-

the combination with a support, of a doorbolt adapted for movement with relation to the support, a bolt-spring connected with the support and adapted to engage With the door-bolt and to'move laterally with relation thereto to release it, a control member pivotally connected with the support and "having connection with the bolt-spring to to be moved laterally to disengage the doorbolt, a control member pivotally connected with the support and having connection with the belt-spring, a stationary member the scope of the subthe control member to engage the secured to the support, and a latch bolt carried by the control member to engage with the stationary member.

3. In a lock ofthe character described, the combination with a vertical support, of a horizontal reciprocatory door-bolt movable with relation thereto, an upstanding bolt-spring having its lower end secured to the support and its upper end adapted Ito move laterally, a vertically swinging control member having'its upper end pivotally connected with the support and connected with the bolt-spring near its pivot, a stationary apertured member secured to the support near the lower end of the control mem ber, a. spring pressed latch bolt carried by a'pertured stationary member, latch bolt against movement. 4. In a. lock of the character described, a combination with a support, of a door-bolt adapted for movement With-relation to the support, a co-acting bar connected With the support and adapted to engage with the door bolt and to be moved laterally with relation thcretebto release it, and a gravity operated control member pivotally connected with the support and having connection with the co-acting bar to move it laterally.

In testimony whereof -We alix our signatures in presence of tivo Witnesses.
